IEEE 802.1Qcc-2018

This standard specifies Media Access Control (MAC) Bridges that interconnect individual Local Area Networks (LANs), each supporting the IEEE 802 MAC service using a different or identical media access control method, to provide Bridged Local Area Networks and Virtual LANs (VLANs).

This amendment describes new protocols, procedures and managed objects for bridges and end stations, which are compatible with existing mechanisms, and provide: - Support for more streams. The current worst case limit is less than 500 streams; there are use cases that require two orders of magnitude greater than this. - Mechanisms that allow Stream Reservation class (SR class) parameters to be configured - Inclusion of additional parameters and mechanisms in the stream reservation protocol that support additional applications, such as higher reliability, latency requirements, and latency changes due to network reconfiguration. - Support for higher layer streaming sessions, such as Real-Time Protocol (RTP)-based sessions. - Deterministic stream reservation convergence. - User Network Interface (UNI) for routing and reservations.

Amendment Standard - Superseded. Enhancements to the configuration of time-sensitive streams are provided by this amendment to IEEE Std 802.1Q-2018.
